An apparatus for manufacturing a semiconductor device and a method of manufacturing the apparatus, the apparatus including a heater configured to heat a target, and a coating layer, the coating layer including a ternary material of transition metal (M)-aluminum (Al)-nitrogen (N) represented by the following Chemical Formula:MAlN,  [Chemical Formula]wherein x and y satisfy the following relations: 0<x<1 and y≥1.

Apparatus for manufacturing a semiconductor device and method of manufacturing the apparatus

A valve apparatus includes a valve block with a main flow path, a first valve installed on the valve block and connected to the main flow path so that when the first valve turns on, a first fluid is supplied from the main flow path to a process chamber via the first valve, and a second valve installed on the valve block and connected to the main flow path so that when the first valve turns off and the second valve turns on, a second fluid is supplied from the main flow path to a waste gas treatment system via the second valve. The main flow path is disposed parallel to a central axis passing through a center of the valve block and two opposing surfaces of the valve block perpendicularly thereto. The main flow path is disposed to be offset from the central axis toward the first valve.

Valve apparatus

A substrate transfer apparatus includes: a chamber including a lower surface, an upper surface opposing the lower surface, and a side surface extending between the lower surface and the upper surface; and a fan filter unit disposed on the upper surface of the chamber and configured to introduce air into the chamber. The chamber includes an inclined surface extending from the upper surface to the side surface and positioned to a side of the fan filter unit.

Substrate transfer apparatus

A hard disk drive includes a base on which at least one disk recording and storing data is provided, a filter provided in an area around a corner of the base with a predetermined air flow space interposed between the corner and the filter to collect contaminant particles in air flowing due to rotation of the disk, and an air exhaust prevention unit provided in an area of the air flow space to prevent the air input to the air flow space through an inlet portion between the filter and a first corner side wall connected to the corner from being exhausted through an outlet portion between the filter and a second corner side wall connected to the corner without passing through the filter. The hard disk drive is manufactured in a simple method without changing the media of the filter and a contaminant particle collection effect is improved.
